FIRE-PLACE HEATER.

SPECIFICATION forming part of Letters Patent No. 405,707, dated June 25, 1889.

Application filed June 8, 1888. Serial No. 276,450. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS B. JACKSON, a citizen of the United States, residing at Belmont, in the county of Belmont and State of Ohio, have invented certain new and useful Improvements in Fire-Place Heaters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a partof this specification.

This invention relates to fire-place heaters of that class which heat by radiation and by hot air, the air being heated in a chamber on each side in the rear and above the firegrate and let into the room in desired quantities through registers which conununicate with the said hot air in chamber. The cold ai conducted to the hot-air chamber through a pipe, which extends to the exterior of the building, and which is provided with a regulating-damper to control the amount of air to be admitted to the said chamber. A branch pipe extends from this cold-air pipe, and is provided with a register, and admits air into the room to moderate the temperature thereof.

The improvement consists in the novel features which hereinafter will he more fully described and claimed, and shown in the annexed drawings, in which- Figure 1 is a front view of the fire-place heater; Fig. 2, a vertical section on the line X X of Fig. 1, showing the cold'air pipe, and the cold-air register connected with the coldair pipe; and Fig. 3, a horizontal. section on the line Y Y of Fig. 1.

The fire-place heater is composed of the bottom A, the sides B, the front C, the back I), the top E, and the fire-chamber composed of the end Walls F, parallel with the sides B, the back G, and the top II, which extends to within a short distance of the front .C, and connects with the vertical wall I, f rom the top of which extends rearwardly the inclined top .I. The rear end of the top .I connects with the back wall G. The air-chamber K, formed between the Walls G, II, I, J, and F F, is located directly above the fire-chamber, and communicates with the aiirchamber. I. in the rear of the lire-chamber, and formed between the backs D and G, through the openings 'i i in the back wall G. The aii.*-chambers K at each end of the fire-chai'nber communicate with and are extensions of the air-ehamber K.

The cold-air pipe L, extending from the exterior of the building, passes through the bottom A. and up through the chamber hi to the chamber K, and is provided with a vertical branch L, that extends through the iloor ol' the room and is provided with the cold-ai r reg ister l. The end of the pipe I. has the damper I, which opens upward, being controlled by the string P, to admit more or less air, as required.

The hot-air registers or communicate with the chambers 1\'.'-, and can be opened more or less to admit the heated air into the room.

The fire-grate N and the back grate N are support-ed between. the end walls F ii. The back grate N is curved in cross-section from top to bottom, and is pivotally supported at its ends midway of its top and bottom on the gudgeons w, and is held in position by thecatch or. The fire-chamber is protected by the end plates 0 and the top plate I, which extends alon gth e top H and part way down the back G.

The products of combustion escape through the space between the front 0 and the front I of the hot-air chamber K, and are directed to the chimney by the hood P. The space in the front 0, directly in front of and above the fire-grate, is closed by the slides or metal screens Q and Q, two being provided for each side, which are suspended from the metal bar q, supported above the fire-chamber. The slides or screens work through slots in the sides F and enter pockets R, formed between the front C and the plates 9", parallel with the said front.

Vhen the fi re is started, the slides are drawn out and effect a strong draft up the chimney, and prevent the escape of smoke into the room. They also protect the eyes from the I glare of the fire and prevent the radiation of too much heat into the room. The grate being pivoted, can. be readily dnmpm'l.

Having thus described my invention, whatI claim, and desire to secure by Letters Patent, is

it. In a fire-place heater, the combination,

with the hot-air chambers K K K and K, arranged to inclese a fire-chamber, the hotair chamber K being directly above the firechamber and closed in on every side and communicating with the hot*air-chamber K, of the cold-air pipe leading directly to the hotair chamber K, substantially as and for the purpose described.

2. The herein-described fire-place heater composed of the 1" rent, the end, and the rear hot-air chambers K and K, respectively, inclosing the fire-chamber, the hot-air chamber K, arranged direetl y over the top of the [ireehamber and communicating with the rear hot-air chamber, the cold-air pipe passing through the rear chamber K. and extending into the chamber K, and lhe eold-air register communicating with the said cold-air pipe, substantially as and for the purpose described. 3. In a fire-place heater having end, rear, and top hot-air chambers arranged to form walls and inclosc the fire-chamber, the combination of the hot-air chamber K, arranged in the top hot-air chamber, the metal end plates 0 O, and the metal top plate 1, extending over the fire-chamber and part Way down in the rear of the fire-chamber, substantially as and for the purpose described.

Tn testimony whereof I aflix my signature in presence of t"'o Witn csses.
